This meta-analysis included 8 trials with 685 patients in total. Results showed that vitamin C decreased the length of mechanical ventilation on average by 14%. Vitamin C showed beneficial effects, particularly in patients with the longest ventilation (most severe diseased patients). In 5 trials, including 471 patients requiring ventilation for over 10 hours, ventilation decreased on average by 25%. More details can be found in the study.
